Description:
TECHNICAL FIELD OF THE INVENTION
[0001]The invention relates to methods for detection of different types of autoimmune antibodies against the receptor for the thyroid-stimulating hormone (TSH receptor) with high specificity, and to new TSH receptor chimeras applicable in this method as binding reagent.
TECHNICAL BACKGROUND OF THE INVENTION
[0002]The TSH receptor (TSH-R) plays a key role in function and growth of thyroid cells. This receptor is a member of a subfamily of G-protein-coupled glycoprotein receptors, which additionally in particular also comprise receptors for the luteinizing hormone/chorionic gonadotropin (LH/CGR) and the follicle-stimulating hormone (FSHR). The receptors of this subfamily have a large N-terminal extracellular domain, which is of essential significance for ligand binding, and for which it was shown, that it is involved in signal transfer. The transfer of the TSHR signal is mainly mediated by activating adenylate cyclase, which results in an increase of the intracellular cAMP level.
[0003]Part of the large interest in the TSH receptor is to be attributed to its role as primary auto-antigen for thyroid gland autoimmune diseases, which are accompanied by the occurrence of auto-antibodies against the TSH receptor. Such thyroid gland autoimmune diseases in particular include Basedow's disease, an autoimmune disease resulting in hyperthyroidism, which is one of the most frequent human autoimmune diseases. Basedow's disease is caused by activation of adenylate cyclase and the resulting cAMP increase. This results in hyperthyroidism, goiter formation, and possibly eye changes. The auto-antibodies against the TSH receptor can also be of a blocking nature, and thus inhibit adenylate cyclase and cAMP. In this case, there is a hypofunction of the thyroid gland. Simultaneous occurrence of stimulating and blocking auto-antibodies in the affected patients is likewise possible, wherein the portion of stimulating antibodies usually predominates.
[0004]For detection of such autoimmune antibodies, there has been a bioassay for some time now, in which the cAMP increase is measured. This measuring method is very time-consuming. Furthermore, the bioassay is not reliable, since it can provide false-positive results. Within the scope of this description, this type of measuring method will be designated as bioassay to differentiate it from the in-vitro methods for determination of autoimmune antibodies against the TSH receptor. In an in-vitro detection method for autoimmune antibodies available on the market, a TSH receptor extracted from pork thyroid gland membrane is used (first generation of in-vitro methods). In another assay for detection of autoimmune antibodies against the TSH receptor, a complete human recombinant TSH receptor protein (wild type) is used in a competition assay (second generation of in-vitro methods).
[0005]Thyroid, Vol. 7 (1997) 867-877 describes the epitopes for stimulating and blocking antibodies at the TSH receptor. The majority of the functional epitopes for stimulating antibodies are located in the range of amino acids 8 to 168, and those for the blocking antibodies in the range of amino acids 261 to 370 of the receptor protein. For activity measurements, the above stated bioassay is used.
[0006]WO 01/27634 A1 for the first time provides a quantitative method for simultaneous detection of autoimmune antibodies of different specificity, which is quickly reproducible and executable with high accuracy. For this purpose, TSH receptor chimeras are used, which differ from the wild type receptor in that individual sequences, to which autoimmune antibodies bind, are substituted with respective sequences of another receptor from the class of G-protein-coupled receptors. The TSH receptor chimeras are based on the complete TSH receptor protein. However, the measuring effort is high. The separation by centrifugation makes the method too cumbersome for routine use. The assay also must be executed in an ice bath or at 4° C., since the TSH receptor chimeras are not very stable. A respective technical teaching can be found in WO 01/63296 A1, where the use of a sandwich technique is suggested for detection. It turned out, however, that usually with the assay materials suggested there, unspecific binding is too high. An assay for detection of autoimmune antibodies on the basis of the findings of the two patent applications stated above is not available on the market.
[0007]For the purpose of this description, a measuring method for detection of autoimmune antibodies available on the market for some time now, which uses the complete unchanged TSH receptor in a competition assay, will be designated as second-generation detection method. This assay is suitable for detection of Basedow's disease. It is, however, disadvantageous that stimulating, blocking and neutral autoimmune antibodies cannot be distinguished. Furthermore, not all subtypes are identified, since the displaced TSH only binds to the epitope for stimulating and blocking auto-antibodies at 30 to 40%.
SUMMARY OF THE INVENTION
[0008]Starting from this state of the art, the object underlying the invention is to modify the method known from WO 01/27634 A1 to further increase the accuracy and expressiveness of this assay, and to make such a method usable for automats.
[0009]This object is solved by a method for differential determination of different types of auto-antibodies directed against the TSH receptor in patient samples using TSH receptor chimeras as binding reagent, in which the sequences of the receptor substantial for binding stimulating and/or blocking auto-antibodies are replaced by respective sequences of another receptor, which do not effect any binding of the respective type of auto-antibodies, by [0010](a) contacting the patient sample with first TSH receptor chimeras bound to a solid phase, wherein an autoimmune antibody with an antigen-binding fragment binds to the first TSH receptor chimera, [0011](b) adding a second, C-terminal-modified receptor chimera, wherein the other antigen-binding fragment of the autoimmune antibody binds to the second C-terminal-modified TSH receptor chimera, and finally [0012](c) admixing a labeled secondary antibody directed against the modified C-terminal epitope of the second receptor chimera, wherein this antibody binds to the modified C-terminal epitope of the second TSH receptor chimera, and triggers a detectable event, or [0013]using a second receptor chimera labeled in such manner, that this chimera can be detected by known detection methods.
[0014]According to a further embodiment, the object underlying the invention, can also be solved by [0015](a) contacting the patient sample with binding agent adsorbed to a solid phase, the binding agent being selected from protein A, protein G, and anti-IgG, to allow binding of an autoimmune antibody from the patient sample to the binding agent, [0016](b) admixing a TSH receptor chimera to the mixture of binding agent adsorbed to a solid phase and patient sample, to allow binding of an autoimmune antibody to the TSH receptor chimera, [0017](c) admixing to the received reaction mixture a labeled modified secondary antibody (F(ab)s), to allow binding of the secondary antibody at the receptor chimera to an epitope of the receptor chimera other than the epitope, to which the autoimmune antibody binds, and wherein the secondary antibody is modified in such manner, that it does not bind to the binding agent adsorbed to a solid phase (Fab regions only), or [0018]using at stage (b) a TSH receptor chimera labeled for executing a common detection.
[0019]Subject of the invention are furthermore TSH receptor chimeras, in which the sequences of the receptor substantial for binding of stimulating and/or blocking auto-antibodies are replaced by respective sequences of another receptor, which do not effect any binding of the respective type of auto-antibodies, and the TSH receptor chimeras are truncated and therefore neither contain the membrane portion nor the intracellular portion of the TSH receptor protein.

[0037]Sequence No. 10 shows the amino acid sequence of a fusion protein from a truncated TSH receptor chimera B (extracellular portion) fused with a gLUC signal peptide sequence and a Gaussia luciferase sequence.
[0038]The TSH receptor chimeras used according to the invention are such for which portions of the amino acid sequence are replaced by comparable sequences of another receptor with a different binding behavior towards TSH receptor autoimmune antibodies, in particular non-binding sequences. Such comparable sequences may for example be sequences of a rat LG-CG receptor. Therefore, those epitopes were substituted in the receptor chimeras used according to the invention, to which stimulating and/or blocking autoimmune antibodies bind. For the TSH receptor chimeras, to which neutral autoimmune antibodies bind, therefore the epitopes for stimulating and for blocking autoimmune antibodies were substituted. These receptor chimeras can be constructed according to Biochem. Biophys. Res. Comun. (1991), 179:70-77 or WO 01/27634. Both documents are incorporated by reference for the purposes of disclosure of this invention.
[0039]Thus, according to the invention, the TSH receptor chimeras A, B and C can be distinguished. For chimera A, preferably the TSH receptor amino acids 8 to 165 can be replaced by substantially the comparable amino acids 10 to 166 of the LH-CGR. For chimera B, preferably the TSH receptor amino acids 261 to 370 can be replaced by substantially the respective amino acids 261 to 329 of a rat LH-CGR. For chimera C, amino acids 8 to 165 as well as amino acids 261 to 370 of the TSH receptor can be replaced by respective LH-CGR amino acids.
[0040]With TSH receptor chimera A blocking autoimmune antibodies, with chimera B stimulating autoimmune antibodies, and with chimera C neutral autoimmune antibodies are detected from a patient sample.
[0041]The TSH receptor extends from the cytosol through the cell membrane into the extracellular space. The extracellular portion of the receptor protein has the binding site for TSH and the autoimmune antibodies. Surprisingly, it was found, that a truncated TSH receptor peptide, which substantially only has the extracellular portion of the TSH receptor protein, can be stored stablely, without loosing its ability to bind TSH. The same was also found for its ability to bind autoimmune antibodies.
[0042]Preferably, the TSH receptor chimeras A, B, or C used according to the invention are only the extracellular portion of the respective TSH receptor chimera (truncated TSH receptor chimera). This applies to the so-called first TSH receptor chimera used in the method according to the invention as well as to the so-called second additionally used TSH receptor chimera. This extracellular portion of the TSH receptor chimera can substantially comprise a peptide of 1 to 418 amino acids. That corresponds to amino acids 1 to 418 of the extracellular portion of the wild type TSH receptor. The preferably used truncated TSH receptor chimeras A, B, and C are thus substantially missing the cytosol and the membrane portion of the known TSH receptor chimeras. The use of the truncated TSH receptor chimeras in the detection methods according to the invention is substantially simpler than that of the complete TSH receptor chimeras known so far.
[0043]Preferably, the TSH receptor chimeras A, B, and C according to the invention are therefor such ones missing the cytosol portion and substantially the membrane portion of the TSH wild type receptor. The extracellular portion of the wild type TSH receptor is in these cases formed as chimera A, B, or C, like described above.
[0044]Particularly advantageous in these truncated TSH receptor chimeras is that for their production in recombined cells, the truncated TSH receptor chimeras A, B, and C are secreted into the extracellular space, when signal peptides or the respective nucleotide sequence, respectively, of, for example, the alkaline phosphatase or the transthyretin are inserted upstream of the TSH receptor chimera nucleotide sequence. Then no digestion of the cells is required to obtain the TSH receptor chimeras A, B, or C. Particularly preferred is the signal peptide of the enzyme transthyretin. In this description of the invention, signal peptide means a peptide residue, which has at least the amino acids required for the secretion of the truncated receptor chimeras from the cell.
[0045]According to a further preferred embodiment, the signal peptide is a constituent of the TSH receptor chimeras, and additionally an enzyme with its secretory signal peptide sequence effective for detection purposes can be contained in the TSH receptor chimera.
[0046]In one embodiment of the invention, the first TSH receptor chimera bound to a solid phase can be fused at its C-terminal end with a peptide. Such a peptide is, for example, a highly immunogenic subsequence of the peptide thyrostimulin or from the C-terminal of the TSH receptor. In this case, the antibody immobilizing the first TSH receptor chimera at the solid phase is a monoclonal or polyclonal antibody directed against this peptide, for example an antibody directed against thyrostimulin.
[0047]In a further embodiment of the invention, a so-called second TSH receptor chimera can be modified at its C-terminal end in such manner, that specific binding of the second TSH receptor chimera to the immobilized antibody, to which a first TSH receptor is bound already with its C-terminal, is avoided. Thus problems like unspecific binding, which can occur in a bridge assay, are suppressed. The use of this second receptor chimera modified in such manner serves the further increase in specificity and sensitivity of the method.
[0048]According to a further embodiment, the modified second TSH receptor chimera described above can be fused at its C-terminal end with a highly immunogenic peptide. Such a peptide can be selected from a subsequence of thyrostimulin or the C-terminal end of the TSH receptor. Such a subsequence can be obtained from the cytosolic portion of the TSH receptor, for example encoded by nucleotides 743 to 763 of the TSH receptor. A second TSH receptor chimera obtained in such manner also has the advantage, that binding of the second TSH receptor chimera to the immobilized antibody, to which a first TSH receptor chimera is bound already with its C-terminal, is avoided. With the presentation of a highly immunogenic peptide residue, a second labeled antibody can be bound simply and specifically. The fusion of a subsequence of the peptide thyrostimulin results in the same advantage. Antibodies against highly immunogenic peptide sequences show high binding affinity. Consequentially, high binding specificity is achieved, whereas unspecific binding is largely reduced.
[0049]The first or second TSH receptor chimera used according to the invention can be modified for detection. This modification can be labeling for detection or labeling by an immunogenic peptide sequence, which is detected by a secondary antibody suitable for detection.
[0050]In the method according to the invention, the so-called first TSH receptor chimeras A, B, and C can be bound to a solid phase. In this case, the binding of the TSH receptor chimeras to the solid phase can take place via an immobilizing antibody, which, for example, is directed against a C-terminal epitope of the TSH receptor chimeras. Such an antibody can be a polyclonal or monoclonal antibody.
[0051]For detection of the binding of an autoimmune antibody to one of the TSH receptor chimeras A, B, or C, a secondary antibody can be used. The secondary antibody can be present in addition to the immobilizing antibody. It can be a monoclonal or a polyclonal antibody. In such embodiments of the method according to the invention, in which the autoimmune antibody binds to protein A, G, or to anti-IgG, the Fc portion of the secondary antibody will be removed to increase the specificity and sensitivity of the assay. Thus, binding of this secondary antibody to protein A, G, or anti-IgG is avoided. The preparation of such antibodies is known and for example described in Journal of Immunological Methods, 138 (1991), 111-119. Available on the market is the ImmunoPure® F(ab')s Preparation Kit of Pierce Biotechnology Inc., Rockfort, Ill. 61105/US, as a tool for separating the Fc portion of an antibody. For this method, immobilized pepsin is used for separating the FC portion of the antibody. A subsequent reaction with 5,5-dithiobis-(2-nitrobenzoic acid) (DTNB), followed by fusion with a peptide, which binds neither to protein A nor to protein G. Such a fusion is for example described in Science 241 (1988), 1353. The documents stated above are incorporated by reference for the purpose of description of the present invention.
[0052]The TSH receptor chimeras used according to the invention, first or second TSH receptor chimera, can be labeled depending on the desired assay design. Direct labeling within the meaning of the invention means labeling of the TSH receptor chimeras. Indirect labeling within the meaning of the invention means the use of a secondary labeled antibody. Labeling can be in such manner, that it directly or indirectly provides a detectable signal.
[0053]Labeling means can be linked with the TSH receptor chimeras or the secondary antibodies by fusion or chemical bond. Preferably, the labeling means are with their N-terminal towards the TSH receptor chimera linked with it.
[0054]Suitable labeling is for example executed using enzymes like alkaline phosphatase (AP), secretory alkaline phosphatase (SEAP), glow-worm luciferase and peroxidase or a dye like an acridine dye, a fluorescent or bio/chemoluminescent material. In the case of the enzymes stated above, their encoding nucleotide sequence is preferably fused with the nucleotide sequence of the TSH receptor chimeras. Suitable labeling is further for example executed by FITC, biotinylation and streptavidin.
[0055]According to further embodiments of the method according to the invention, proteins A, G, or an anti IgG can be immobilized at a solid phase for binding an autoimmune antibody.
[0056]Suitable solid phases comprise plastic bodies like plastic tubes, plastic platelets and magnetic and non-magnetic plastic particles. Plastics suitable for the solid phases used according to the invention are such ones, which allow binding of proteins by chemical or physical reaction. These include beads, microtiter plates and tubes, which can consist of polystyrene, polyethylene or other known polymer materials. Such solid phases are known to the person skilled in the art, and are commercially available.
[0057]The truncated TSH receptor chimeras according to the invention can be stored lyophilized. They can be stored in a lyophilized form bound to a solid phase via a monoclonal or polyclonal antibody. For the detection reaction, reconstitution of the lyophilized components takes place by dissolution in an assay buffer.
[0058]The truncated TSH receptor chimeras according to the invention show high stability in their dissolved form. They remain stable at 4° C. for 4 to 7 days, at 24° C. for 3 to 6 days, and at 37° C. for 24 hours. These conditions are also suitable for the execution of the detection method according to the invention on automats, on which the components are stored at 4° C., while the test reaction can take place at 37° C. without a problem. In contrast, the complete TSH receptor chimera remains stable at 4° C. for 3 to 6 days, at 24° C. for 24 to 48 hours, and at 37° C. for only 3 hours.
[0059]In the determination of TSH auto-antibodies in the serum of patients suffering from Basedow's disease according the method of the invention, good values could be determined for the interassay variation coefficient of 4 to 12%. The intraassay precision lies clearly below 10%. The method according to the invention is excellently suitable for the automated detection of autoimmune antibodies in patient samples. For the execution of the method according to the invention, one of the three TSH receptor chimeras is added to respectively one patient sample, and the sample is then investigated for the respective autoimmune antibody.
[0060]Exemplary embodiments of the methods according to the invention are described in the following with reference to the figures.
[0061]FIG. 1 shows an embodiment of the method according to the invention, in which a truncated TSH receptor chimera bound to a solid phase has been contacted with a patient sample. An autoimmune antibody has bound to the respective epitope of the TSH receptor chimera. A second receptor chimera modified at its C-terminal by a highly immunogenic peptide is then admixed to the reaction mixture. The second, still free epitope in the Fab portion of the patient's autoimmune antibody then binds to the second receptor chimera. The detection of the autoimmune antibody takes place with a secondary labeled antibody binding to the highly immunogenic peptide of the C-terminal of the second TSH receptor chimera.
[0062]In the embodiment of FIG. 2, such a second truncated TSH receptor chimera is used, which is modified with a labeling means at its C-terminal end. In this case, no secondary labeled antibody is required.
[0063]FIG. 3 shows a method, in which the immobilizing antibody is an antibody directed against the peptide thyrostimulin. The first TSH receptor chimera is a truncated receptor chimera, which at its C-terminal end is fused with the peptide thyrostimulin. The second receptor chimera likewise comprises only the extracellular portion of the receptor chimera, and is labeled at its C-terminal end. The autoimmune antibody binds to the first as well as to the second TSH receptor chimera.
[0064]FIG. 4 shows a procedure according to the invention, in which proteins A, G, or an anti-IgG are immobilized at a solid phase, and have been contacted with a patient sample. The patient's autoimmune antibody binds with its Fc portion to proteins A, G, or anti-IgG. Following the addition of a TSH receptor chimera, the patient's autoimmune antibody binds with its Fab portion to the respective epitope of the TSH receptor chimera. For detection of the binding, a secondary labeled antibody is used, which does not have a Fc region, so that binding to proteins A, G, or anti-IgG is suppressed.
[0065]Alternatively, as shown in FIG. 5, labeling can have taken place at the C-terminal end of the TSH receptor chimera. Thus, the autoimmune antibody can be detected by a respective detection reaction with the TSH receptor chimera.
[0066]It is also possible to assay a patient sample for the presence of several TSH autoimmune antibodies. For this purpose, for example first the detection of blocking or neutral TSH autoimmune antibodies can be executed with chimeras A or C. In a further assay run, chimera B is admixed to the same patient sample, and the method according to the invention is executed.
[0067]Exemplary TSH receptor chimeras B and A according to the invention are explained in the following.

Cell Culture
[0098]HEK293 cells were cultured in Dulbecco's Modified Eagle's Medium supplemented with 10% fetal bovine serum. The cells were cultivated under a 5% CO2 atmosphere at 37° C.
Construction of TSHR/LH-CGR Chimeras
[0099]Three different chimeras of the human TSHR, subsequences of which were replaced by respective sequences of a rat LH-CGR, were constructed according to the description in Biochem. Biophys. Res. Commun. (1991), 179: 70-77. For one of the chimeras, hereinafter designated as "chimera A", the TSHR amino acids 8 to 165 were replaced by the comparable amino acids 10 to 166 of LH-CGR; for "chimera B", the TSHR amino acids 261 to 370 were replaced by the comparable amino acids 261 to 329 of a rat LH-CGR, while in the case of "chimera C", amino acids 8 to 165 as well as amino acids 261 to 370 were replaced by comparable LH-CGR amino acids.
[0100]In particular, the plasmid pcDNA3-rLHR (B9) was taken as the basis for that, which contains the sequence for the rat LH-CGR receptor. The DNA sequences, which encoded for amino acids 10 to 165 as well as 261 to 329, were multiplied according to the PCR technique using the primer pairs P1-P2 and P3-P4, respectively, containing NsiI, AatII, BfrI or SacI, respectively, restriction sites, whereby NsiI/AatII or BfrI/SacI-PCR, respectively, fragments were obtained. In parallel to that, a pTM1-TSHR-FLAG-6HIS plasmid, obtained according to DE 196 45 729 or Exp. Clin. Endocrinol. Diabetes 5: 282-290 (1997), was digested with PstI-AatI or BfrI-SacI restriction endonucleases. The fragments produced in that were removed and replaced by the PCR fragments obtained from the rat LH-CG receptor, whereby the cDNA sequences for the different TSHR/LH-CGR chimeras A, B, and C are obtained.
[0101]The vector pTM1-TSHR-FLAG-6HIS, or the new vector with the TSHR/LH-CGR DNA (PTM1-TSHR/LH-CGR) obtained from it, was linearized with Ava I and the "sticky" ends filled using Klenow polymerase. The vector pIRESneo was linearized with Cla I and the "sticky" ends filled using Klenow polymerase. The TSHR or TSHR/LH-CGR, respectively, fragment intended for expression, was excised using Bam HI and sub-cloned into the Cla I (filled site)/Bam I site of the expression vector pIRESneo. This results in the expression vectors pIRESneo-TSHR or pIRESneo-TSHR/LH-CGR, respectively, for cell transfection and expression of the various TSH receptor chimeras and also for modifications of the chimeras.
Preparation of the Extracellular Portion of the TSH Receptor Chimeras
[0102]The TSH receptor chimera B (wild type), cloned into the expression vector pIRESneo, is used as a template for the preparation and amplification of the nucleotide sequence with polymerase chain reaction (PCR) for the extracellular portion of the TSH receptor chimera B. The two primers required for the PCR contain the following nucleotide sequences: primer V contains a sequence of 6 nucleotides for the restriction enzyme EcoR V and a sequence of 18 nucleotides for the N-terminal peptide sequence in chimera B without a signal peptide. Primer 6 contains the nucleotide sequence for amino acids 261 to 266 together with the sequence of 6 nucleotides for Bam H1.
Insertion of the TSH Receptor Chimera B Nucleotide Sequence (Extracellular Portion Only) into Expression Vector
[0103]The obtained PCR product contains the nucleotides encoding for amino acids 21 to 266. This sequence is inserted into pIRESneo via EcoR V and Bam I interfaces.
Fusion of the Nucleotide Sequences of the Extracellular TSH Receptor Chimera B and the Enzyme SEAP
[0104]First, the two following primers were prepared as precondition for the subsequent fusion with pSEAP-2. Primer 7 contains the nucleotides for the N-terminal amino acid sequence of SEAP and the nucleotides for EcoR V. Primer 8 contains the nucleotides for the C-terminal amino acid sequence of SEAP together with the nucleotides of Eco 47III. Herewith, amplification of this template takes place by a polymerase chain reaction.
Insertion
[0105]Then the insertion of the fused nucleotide sequence into pIRESneo-chim B after its splitting at the EcoR V interface takes place. Using restriction analysis with the enzymes EcoR V and Bam HI, clones with the fused nucleotide sequence are selected (according to probability, 50% of the clones SEAP will be contained with the wrong orientation, which then in the restriction analysis differ from the correct fusion nucleotide sequence by a shorter length).
Incorporation of a Secretory Signal Peptide Sequence
[0106]This process takes place with the same genetic engineering methods like stated above under fusion and insertion. Here, in particular, the signal peptide sequence of transthyretin is used, since it effects a high secretion performance for the high-molecular globulin transthyretin.
Expression and Collection of Fusion Proteins TSHR-SEAP and TSHR/LH-CGR-SEAP, Respectively, as a Cell Extract
[0107]Confluent stable HEK293 cells are cultured in 10 to 20 75 cm2 plates (approx. 20×106 cells). After scraping off, the cells are transferred into phosphate-buffered saline solution (PBS), and washed four times with PBS under centrifugation at 2500 rpm. The cells obtained were lysed in 0.3 ml of a buffer A (20 mM Hepes-KOH; pH 7.5; 50 mM NaCl; 1% Triton X100; 10% glycerol) under freezing and thawing. The suspension obtained was centrifuged at 30,000 G for 1 hour, the supernatant (approx. 8 mg/ml of total protein) was collected and stored at -70° C.
[0108]The supernatant obtained in that manner (extract) can be used in determination methods as TSHR-SEAP or TSHR/LH-CGR-SEAP, respectively.
Preparation of Cell Fractions
[0109]The HEK193 cells were pelletized by centrifugation at 1,200 rpm. The cell pellet obtained was re-suspended in 0.3 ml of a buffer, which contained in 10 mM Tris-HCl, pH 7.6, 50 mM NaCl, 10% glycerol as well as a protease inhibitor mixture. The suspension was then homogenized at 4° C. by 20 stroke movements in a glass-teflon homogenizer, and then centrifuged for 15 min. at 800 G, and subsequently for 1 hour at 30,000 G. The supernatant (the cytoplasma fraction) was collected. The membrane pellet was processed by homogenizing it at 4° C. by 20 stroke movements in a glass-teflon homogenizer in 0.3 ml of 1% triton X100 in the same buffer, and then centrifuging it at 30,000 G for 1 hour. The supernatant (triton X100 membrane extract) was collected and stored at -70° C.
Collection of the Secreted Extracellular Fusion TSHR Chimeras
[0110]The truncated, extracellular domains of the fusion TSH-R chimeras are secreted into the culture supernatant by the cells expressing them. The secreted receptor proteins are directly used in the assay in the form of certain dilutions in the assay buffer. For example, 10 μl of extracellular SEAP-TSH-R chimera B from 5 ml of culture supernatant are used in a final dilution of 1:10 per determination.
Generation of a Standard Calibration Curve
[0111]For the generation of a standard curve, a standard solution WHO 90/672 with a standardized concentration of autoimmune antibody was used. The initial solution of the standard contains 100 IU/l, which were diluted for the purposes of generation of the standard curve. As zero value, the serum of a subject without autoimmune antibody in TXBW buffer was used.
[0112]The TSH receptor chimeras B used are stored lyophilized on microtiter plates fixed via antibody, and are reconstituted in buffer with protein stabilizers before their use. The triton X100 wash buffer (TXWB) contains 0.1% TX-100, 50 mM Tris/HCl pH 8.0, 100 mM NaCl. The serum dilution buffer contains 5% glucose and 5% milk powder in TXWB.
[0113]50 μl of sample solution (dilutions of the standard and zero sample) per cavity are diluted with dilution buffer 1:2 and incubated on microtiter plates at room temperature (approx. 22° C.) for 90 minutes. Four washings take place with 300 μl of TXWB each. Then 10 μl of a 1:100 dilution from 5 ml of culture supernatant of a culture dish with a diameter of 10 cm of extracellular TSH receptor chimera, fused with an enzyme SEAP, are added to 90 μl of TXWB. Subsequently, incubation takes place under agitation (300 to 400 rpm) at 37° C. for 30 minutes. Then four washings take place with 300 μl of TXWB. The bio/chemo-luminescence is measured with the Centrol® IA LB 296 microtiter plate measuring device of Berthold GmbH, Bad Wildbad, Schwarzwald, Germany, using Tropix® (reagent for ECL (enhanced chemo-luminescence)) of Applied Biosystems, Foster City, Calif., USA.
[0114]The detection limit is approx. 0.2 IU/l. There exists a polynomial function between relative light units (RLU) and the concentrations of the standard for stimulating auto-antibodies over an area ranging up to at least 40 IU/l.
[0115]In FIG. 6, the relation of the relative light unit (RLU) of the RLU (B=bound) measured in the samples of the dilution series of the TSH receptor auto-antibody standard respectively in relation to the zero value of a subject without autoimmune antibody (B0) is shown on the Y-axis as B/B0. On the X-axis, the dilution of the standard samples is stated. The measurement values, averages from double determinations, are shown in the following table.

Comparison of the Assay According to the Invention with the Competition Assay of the "Second Generation"
[0116]Serum or plasma samples are extracted from venous blood within 3 hours. Storage is possible at 4° C. over a period of 7 days or at -20° C. for 1 to 2 years. Secondary antibodies (see above) are stored at -20° C., and thawed at room temperature before their use in the assay. TSH receptor chimeras are stored lyophilized on microtiter plates, and reconstituted in buffer with protein stabilizers before their use. Triton X100 wash buffer (TXWB) contains 0.1% TX-100, 50 mM Tris/HCl pH 8.0, 100 ml NaCl. Serum dilution buffer contains 5% glucose and 5% milk powder in TXWB.
[0117]50 μl of serum or plasma per cavity are diluted with buffer TXWB 1:2, and incubated on microtiter plates at room temperature (approx. 22° C.) for 90 minutes. Then 10 μl of a 1:10 dilution of 5 ml of culture supernatant of a culture dish with a diameter of 10 cm of extracellular TSH receptor chimera, fused with an enzyme SEAP, are added to 90 μl of TXWB. Subsequently, incubation takes place under agitation (300 to 400 rpm) at 37° C. for 30 minutes. Then four washings take place with 300 μl of TXWB. The bio/chemo-luminescence is measured with the Centrol® IA LB 296 microtiter plate measuring device using Tropix®.
[0118]FIG. 8 shows by way of comparison the measurement results achieved with patient serums using the method according to the invention and using an assay of the so-called second generation. In the second-generation assay, a complete TSH receptor--no receptor chimera--was used in a competition assay. For that, the TSH receptor is immobilized at a solid phase and contacted with sample serum and labeled TSH. The concentration of the TSH used was varied. Autoimmune antibodies displace TSH from the receptor. The signal change effected by the displacement is used as measurement value.
[0119]The analysis design of the assay according to the invention was that of FIG. 2. The execution of the competition assay took place according to the instructions of the assay kit TRAK® of B.R.A.H.M.S. AG, 16761 Hennigsdorf, Germany, which was used.
[0120]In FIG. 8, the international units per liter determined according to the invention are stated on the Y-axis, and those according to the second-generation method on the X-axis of the diagram. The analysis shows, that for a total of 41 patient serums the sTRAb values are lower than the TRAK values in 14 cases, and higher in 19 cases.
[0121]Although the invention was described above with reference to certain embodiments, changes and modifications are possible, which are apparent for the person skilled in the art and which do not exceed the scope of the patent determined by the claims.
